This study investigated the artificial propagation of peppermint shrimp (Lysmata boggessi Rhyne & Lin, 2006) by exploring the relationships among carapace length, number of larvae, different feeding concentrations, starvation, salinity and temperature on the growth and survival of the shrimp. The relationship between the number of hatched larvae (Nlarva) and carapace length (CL) of broodstock was expressed as the regression equation Nlarva = 0.528CL3.8559. The period from spawning to hatching was negatively correlated with water temperature, and the accumulated hatching temperature was 293.4 ± 34.5 degree-days. Larvae fed with the nauplii of Artemia spp. at 0.5-4/ml had better survival rate and growth at 6 dph (days posthatch). In terms of salinity, the survival rate and growth were better in salinities ranging from 24-39 psu. The survival rate and growth were decreased, however, in larvae that were not fed immediately after being hatched. Furthermore, better survival rates were obtained for larvae raised at temperatures of 18, 21, 24 and 27℃, while better growth rates were obtained for larvae raised at temperatures of 27,30 and 33℃. Overall, the best survival rate and growth were obtained for larvae raised at 27℃, 34 psu, and fed with the nauplii of Artemia spp. at 2- 4/ml. The larvae developed into postlarvae at 36-104 dph.
